Answer: i wish i could help but that’s a lot
Explanation:
It would be 0 as the rock is not accelerating.
In mathematical form, F=ma= 2*0=0
Answer:
(a) Energy will be 675 J
(B) charge will be 450 C
(C) Total number of particles will be
Explanation:
We have given that a flashlight uses 0.75 watts of power
So power P = 0.75 watt
Voltage is given as V = 1.5 volt
Time is given as t = 15 minutes
We know that 1 minute = 60 sec
So 15 minutes =
(A) We know that energy is given by
(b) We know that energy is also given by
So
Now we have given charge on each particle
So number of charge particle
Answer:
N = 25795 loops
Explanation:
The magnetic field of a solenoid can be calculated by using the following formula:
where,
N = No. of loops = ?
B = Magnetic Field = 0.78 T
L = Length of solenoid = 32 cm = 0.32 m
I = Current = 7.7 A
μ = permeability of free space = 4π x 10⁻⁷ N/A²
Therefore,
<u>N = 25795 loops</u>
Given
hypotenuse is 36
base is 24
Procedure
Cos function (or cosine function) in a triangle is the ratio of the adjacent side to that of the hypotenuse. The cosine function is one of the three main primary trigonometric functions and it is itself the complement of sine(co+sine).
The answer would be 48 degrees
